Problems solved by technology

[0003] In addition, wastewater from chemical plants and oil and natural gas collection and processing plants contains various substances, such as organic pollutants, Cl - , SO 4 2- 、Na + , Ca 2+ Plasma, if these high-salt, high-organic waste water is discharged directly without treatment, it will inevitably cause great harm to aquatic organisms, domestic drinking water, and industrial and agricultural production water. However, the existing waste water salt extraction equipment has complex structures and various processes. , high cost and other shortcomings, especially easy to pollute the environment, therefore, it is urgent to develop a salt extraction equipment with simple and novel structure, safety, environmental protection and low cost

Embodiment 1

[0029] Such as figure 1 , figure 2 As shown, a waste water salt extracting device includes an extraction box 1, in which a water tank 3, a combustion chamber 2 and a waste water tank 4 are sequentially arranged from bottom to top, and the combustion chamber 2 is provided with a furnace door 201 , to provide heat for the extraction tank 1 to concentrate waste water, the purpose of the bottom of the water tank 3 being set close to the combustion chamber 2 is that the combustion chamber 2 provides heat for the water tank 3, and promotes the generation of water vapor in the water tank 3, the water tank 3 and the combustion chamber 2 The two steam pipes 8 are connected, and after the water vapor enters the combustion chamber 2 along the steam pipe 8, it helps complete combustion in the combustion chamber 2, reduces black smoke emission, and is safe and environmentally friendly. In some other embodiments, the water tank 3 is arranged close to the side wall of the combustion chambe...

Embodiment 2

[0034] The same part of this embodiment and Embodiment 1 will not be described again, the difference is:

[0035] Such as Figure 4 As shown, the waste water tank 4 is provided with a heat dissipation and smoke exhaust pipe 10 , and the heat dissipation and smoke exhaust pipe 10 is arranged in a spiral shape along the bottom surface of the waste water tank 4 . In some other embodiments, the heat dissipation and smoke exhaust ducts 10 may also be arranged in a staggered manner.

Abstract

The present invention relates to an apparatus for extracting salts from wastewater, and belongs to the technical field of wastewater treatment equipment. The apparatus comprises an extraction box, wherein a combustion chamber, a water box and a wastewater groove are arranged in the extraction box, the combustion chamber and the water box are communicated through at least a steam pipeline, the top portion of the combustion chamber is provided with at least a heat dissipation and flue discharging pipeline, the heat dissipation and flue discharging pipeline penetrates through the side wall of the wastewater groove and is spirally arranged inside the wastewater groove, and a dragon-type combustion channel is arranged in the combustion chamber. According to the present invention, the wastewater is subjected to rapid concentration salt extraction by using the heat generated by the combustion chamber, such that the stricture is simple, and the cost is low; the heat dissipation and flue discharging pipeline is spirally arranged and the dragon-type combustion channel is arranged, such that the contact area of the heat dissipation and flue discharging pipeline and the wastewater is easily increased, the heat utilization rate can be improved, and the concentration process can be accelerated; and the combustion chamber supplies the heat for the water box to promote the water box to produce water vapor inside, such that the complete combustion is easily achieved in the combustion chamber, the black flue emission can be reduced, and the advantages of safety and environmental protection are provided.

Description

technical field [0001] The invention belongs to the technical field of waste water treatment equipment, in particular to a waste water salt extraction device. Background technique [0002] According to the "2015-2020 China Sewage Treatment Industry Market Prospect and Investment Strategic Planning Analysis Report Prospect", 70% of China's 1.3 billion population drink groundwater, and more than 400 of the more than 660 cities use groundwater as their drinking water source . At the same time, the report pointed out that 90% of the urban groundwater in the country has been polluted. Therefore, the purification treatment of polluted effluent water from domestic and production has attracted great attention from various fields. [0003] In addition, wastewater from chemical plants and oil and natural gas collection and processing plants contains various substances, such as organic pollutants, Cl - , SO 4 2- 、Na + , Ca 2+ Plasma, if these high-salt, high-organic waste water ...
